Provided are a silver element containing silver acetonedicarboxylate with high silver content, and capable of providing a silver element with excellent electrical conductivity, flatness, and adhesivity through heating even for a short time at a low temperature of below the decomposition temperature of the silver salt, and having excellent storage stability, as well as a substrate having a silver element formed thereon with the composition. The composition is characterized by a particular ratio of silver compound (A) represented by formula (1) and amine compound (B) represented by formula (2):
(R 1 : H, -(CY 2 )a-CH 3 , -((CH 2 )b-O-CHZc-CH 3 ; R 2 : -(CY 2 )d-CH 3 , -((CH 2 )e-O-CHZ)f-CH 3 , Y: H, -(CH 2 )g-CH 3 ; Z: H, -(CH 2 )h-CH 3 ; a: 0-8; b: 1-4; c: 1-3; d: 1-8; e: 1-4; f: 1-3; g: 1-3; h: 1-2). |
